Why Scissor Lift ?'
The scissors lift 1s an e1evator with a system of
levers and hyd rau l ic cylinders on which the
metal platform is capabfe of moving in the
verticaI direction, This is achieved by using
of linked, folding supports in a crisscross
pattern, calredscissor mechanism. Scl-ss.ors

.an d bu flding objects. The key advantage of
lifts is tlhat they even offer the best nay to
organi se a technologlcal and industrlaI
proc-ess. Bes.ides , almost au lifts give the
posslblIlty to change the place of their lns
talllat lon without much effort, whleh Is
important In the frequently changing
condftlons In the productlon process these
days. The.scissors 11ft hasat.able surface
